Kin recognition loss following anesthesia in beetle larvae (Aleochara bilineata, Coleoptera, Staphylinidae)

Kin recognition is a complex cognitive process, where an individual should detect a phenotypic cue and compare it to an internal template, which might be genetically determined (i.e., innate or acquired). Kin recognition mechanisms will depend on whether previous encounters with kin are possible or not to form the individual internal template. When relatives have never met before, kin recognition is supposed to rely on recognition alleles (which allows the innate recognition of relatives bearing them), or on self-referent phenotype matching (the individual has formed a template using its own phenotype and recognizes as kin individuals which match it closely enough). Although self-referent phenotype matching is in theory the more likely explanation, it has not been possible so far to exclude experimentally the recognition alleles’ hypothesis. Here, we report that kin recognition in the solitary parasitoid larvae of Aleochara bilineata (Coleoptera; Staphylinidae) is suppressed following carbon dioxide anesthesia or chill-coma, both treatments known to cause a temporary amnesia. Treated larvae superparasitize indifferently hosts parasitized either by siblings or by non-kin larvae, while untreated larvae avoid hosts occupied by siblings. The two types of anesthesia thus suppress kin recognition, but their global effect on larvae is different. Chill-coma suppresses the ability to distinguish parasitized from unparasitized hosts and reduces parasitism rate, suggesting an aspecific impairment of sensory receptors or cognition. However, carbon dioxide narcosis only impairs kin recognition, strongly suggesting that an intact memory is necessary for kin recognition to take place. Although this study does not address the recognition alleles’ hypothesis per se, our results strongly support a self-referent phenotype matching mechanism. On the whole, kin recognition in A. bilineata larvae is effective through short-term memory, because it is affected by amnesic treatments.     

Colour blindness adversely impacts face recognition

ABSTRACT

Whether colour information contributes to the process of face recognition remains controversial. We examine this question here by evaluating the face recognition performance of individuals who are colour blind. Specifically, we compared the performance profile of colour blind and matched control individuals on a colour face recognition task where shape information was progressively degraded. The colour blind participants performed significantly more poorly than controls on this task, as revealed through multiple dependent measures. There was, however, no difference between these two groups on a standardized grayscale control task of face recognition, ruling out a generic face recognition deficit. These results both uncover a face recognition deficit in colour blind individuals and provide evidence for the contribution of colour to everyday facial recognition.     

A signal detection analysis of the recognition heuristic

The recognition heuristic uses a recognition decision to make an inference about an unknown variable in the world. Theories of recognition memory typically use a signal detection framework to predict this binary recognition decision. In this article, I integrate the recognition heuristic with signal detection theory to formally investigate how judges use their recognition memory to make inferences. The analysis reveals that false alarms and misses systematically influence the performance of the recognition heuristic. Furthermore, judges should adjust their recognition response criterion according to their experience with the environment to exploit the structure of information in it. Finally, the less-is-more effect is found to depend on the distribution of cue knowledge and judges’ sensitivity to the difference between experienced and novel items. Theoretical implications of this bridge between the recognition heuristic and models of recognition memory are discussed.     

The effect of changes in posture and clothing on the development of unfamiliar person recognition

In contrast to face recognition little is known about the development of unfamiliar whole‐person recognition. Various cues in a person's appearance may contribute to recognition performance. An age‐related influence of different features on person recognition performance is possible. Here, we investigated two variable features of person recognition, namely posture and clothing, in 4‐year‐olds, 6‐year‐olds, 8‐year‐olds, 10‐year‐olds and adults. The experimental methodology of a short‐term recognition‐test with an immediate four alternative forced choice (4AFC)‐array was used. Targets were shown for 5 seconds. Experiment 1 clearly indicates that a variation of both posture and clothing decreases performance in all age groups compared to a standard, i.e. a no‐change condition. An interaction age×variation of posture and clothing was not observed. In order to untangle the two aspects of posture and clothing, Experiment 2 varied only posture between encoding and recognition. An age‐effect was shown, but no other significant result occurred. Experiment 3 investigated variation of clothing only, and found main effects of clothing and age. Because there was no interaction between the two factors we infer that a change of clothing impairs all subjects' recognition performance. Children's person recognition performance suffers in a way similar to adults' person recognition performance when clothing is varied. In contrast, changing posture does not necessarily decrease recognition accuracy, neither in children nor in adults. No developmental gains were found for dealing with the transformation of posture and clothing between the encoding and recognition phase. Copyright © 2003 John Wiley & Sons, Ltd.

催产素对情绪识别的影响及其机制

催产素(oxytocin)被称为“社会键(social bonds)荷尔蒙”, 时刻影响着社会行为和认知, 其中包括情绪识别。目前, 关于催产素对情绪识别的影响主要有3种观点：(1)催产素选择性地促进个体对积极情绪的识别、减慢对消极情绪的识别; (2)催产素选择性地增强对消极情绪的识别; (3)催产素提高对所有情绪的识别, 与情绪效价无关。催产素影响情绪识别神经机制的研究主要集中在3个方面：情绪效价、性别差异和精神疾病。此外, 还运用社会显著假说解释催产素对情绪识别的作用。催产素可能对情绪识别障碍类精神疾病有潜在的治疗效果, 未来的研究应深入探究催产素与情绪效价的关系, 考虑性别等个体因素的影响, 进一步探讨催产素的临床应用并拓展研究范围。     

Successive Tests of Pair Recognition

A large number of experiments have found a moderate degree of dependence between subsequent tests of recognition and cued recall as described by the TWfunction. This paper investigates the dependence in word pair recognition. Tests of word pair recognition are conducted with the subsequent test being free recall, cued recall, recognition, and cued recognition. The dependence is compared to subsequent tests of cued recognition (i.e. recognition of a target with the presence of a cue). The results are related to a general theory of memory called TECO (Target, Event, Cue, & Object, see Sikström 1996b). This theory makes different quantitative predictions depending on the number of shared connections in the subsequent tests. Using a function suggested by TECO, different degrees of dependencies are predicted for pair and cued recognition. The predictions of the TECO-function show a non-significant deviation from observed data, whereas those of the TW-function deviate significantly in all conditions.     

Exploring the relationship between mindfulness,compassion and unfamiliar face identification

ABSTRACT

Research has related empathy to face recognition. Empathy is proposed as part of compassion, while compassion relates to self-compassion and mindfulness, which may be more effective in face recognition than empathy alone. Experiment 1 investigated the relationship between compassion, self-compassion and empathy, and unfamiliar face recognition memory and matching. Self-compassion, including its facets of mindfulness and common humanity, were related to better recognition, but not matching. Results did not support a relationship between face identification and empathy or compassion. Experiments 2 and 3 further investigated common humanity and mindfulness and found both constructs to relate to face recognition memory. Furthermore, aspects of mindfulness (i.e., act aware and describe) positively related to face recognition. Experiment 3 used an array matching task to further show that matching did not relate to mindfulness or common humanity. The present findings may inform new directions in face recognition research, aiming to practically assist face recognition.     

Mutual mother–offspring vocal recognition in an ungulate hider species (<Emphasis Type="Italic">Capra hircus</Emphasis>)

Parent–offspring recognition can be essential for offspring survival and important to avoid misdirected parental care when progeny mingle in large social groups. In ungulates, offspring antipredator strategies (hiding vs. following) result in differences in mother–offspring interactions, and thus different selection pressures acting on the recognition process during the first weeks of life. Hider offspring are isolated and relatively stationary and silent to avoid detection by predators, whereas follower offspring are mobile and rapidly mix in large social groups. For these reasons, hiders have been suggested to show low offspring call individuality leading to unidirectional recognition of mothers by offspring and followers high offspring call individuality and mutual recognition. We hypothesised that similar differences would exist in hider species between the hiding phase (i.e. unidirectional recognition) and the phase when offspring join social groups (i.e. mutual recognition). We tested these predictions with goats (Capra hircus), a hider species characterised by strong mother–offspring attachment. We compared the individuality of kid and mother calls, and the vocal recognition ability, during the early phase of life when kids are usually hidden and later when kids have typically joined social groups. Contrary to our predictions, we found that both kids and mothers had individualised contact calls and that mutual recognition existed even during the hiding phase. The large differences in the duration of the hiding phase and in the rate of mother–offspring interactions (possibly partially driven by domestication in some species) probably cause variations among hider species in the mother–offspring recognition process.     

Knowing who knows what and who knows whom: Expertise recognition,network recognition,and individual work performance

We tested the relationship between individuals' expertise recognition and work performance, the role of job resourcefulness (i.e. individuals' ability to garner resources to overcome obstacles) as a mediator, and network recognition as a moderator in the link between expertise recognition and job resourcefulness. We found that the positive impact of expertise recognition on work performance was mediated by job resourcefulness, but network recognition did not play a moderating role.     

Item-specific effects in recognition failure: Reasons for rejection of the Tulving-Wiseman function

The present paper addresses the problems of whether recognition failure of recallable words is a function of both recognition and recall, and whether recognition failure is restricted to a small and specifiable subset of study items. A meta-analysis of the Nilsson—Gardiner database (Nilsson & Gardiner, 1993) showed that recognition given recall was positively correlated with recognition and negatively correlated with recall. Two new experiments are reported, the first one using 48 word pairs for which recognition failure was found in previous studies. An item analysis of the data demonstrated that recognition failure occurred primarily with noun—adjective pairs. The second experiment compared Norwegian—American and American—Norwegian name pairs. Wide deviation from the Tulving—Wiseman function (Tulving & Wiseman, 1975) was observed for the latter condition. In both conditions, recognition failure occurred with only the items for which the beginnings of names shared three or more letters. It is concluded that recognition failure occurs when there exists a relationship between the members of an A—B pair that is independent of their pairing in the study context. The Tulving—Wiseman function is the result of collapsing across items in the analysis of previous studies.     

The role of color information on object recognition: a review and meta-analysis

In this study, we systematically review the scientific literature on the effect of color on object recognition. Thirty-five independent experiments, comprising 1535 participants, were included in a meta-analysis. We found a moderate effect of color on object recognition (d = 0.28). Specific effects of moderator variables were analyzed and we found that color diagnosticity is the factor with the greatest moderator effect on the influence of color in object recognition; studies using color diagnostic objects showed a significant color effect (d = 0.43), whereas a marginal color effect was found in studies that used non-color diagnostic objects (d = 0.18). The present study did not permit the drawing of specific conclusions about the moderator effect of the object recognition task; while the meta-analytic review showed that color information improves object recognition mainly in studies using naming tasks (d = 0.36), the literature review revealed a large body of evidence showing positive effects of color information on object recognition in studies using a large variety of visual recognition tasks. We also found that color is important for the ability to recognize artifacts and natural objects, to recognize objects presented as types (line-drawings) or as tokens (photographs), and to recognize objects that are presented without surface details, such as texture or shadow. Taken together, the results of the meta-analysis strongly support the contention that color plays a role in object recognition. This suggests that the role of color should be taken into account in models of visual object recognition.     

Children's haptic and cross-modal recognition with familiar and unfamiliar objects

Five-year-old children explored multidimensional objects either haptically or visually and then were tested for recognition with target and distractor items in either the same or the alternative modality. In Experiments 1 and 2, haptic, visual, and cross-modal recognition were all nearly with familiar objects; haptic and visual recognition were also excellent with unfamiliar objects, but cross-modal recognition was less accurate. In Experiment 3, cross-modal recognition was also less accurate than within-mode recognition with familiar objects that were members of the same basic-level category. The results indicate that children's haptic recognition is remarkably good, that cross-modal recognition is otherwise constrained, and that cross-modal recognition may be accomplished differently for familiar and unfamiliar objects.     

Face age and sex modulate the other-race effect in face recognition

Faces convey a variety of socially relevant cues that have been shown to affect recognition, such as age, sex, and race, but few studies have examined the interactive effect of these cues. White participants of two distinct age groups were presented with faces that differed in race, age, and sex in a face recognition paradigm. Replicating the other-race effect, young participants recognized young own-race faces better than young other-race faces. However, recognition performance did not differ across old faces of different races (Experiments 1, 2A). In addition, participants showed an other-age effect, recognizing White young faces better than White old faces. Sex affected recognition performance only when age was not varied (Experiment 2B). Overall, older participants showed a similar recognition pattern (Experiment 3) as young participants, displaying an other-race effect for young, but not old, faces. However, they recognized young and old White faces on a similar level. These findings indicate that face cues interact to affect recognition performance such that age and sex information reliably modulate the effect of race cues. These results extend accounts of face recognition that explain recognition biases (such as the other-race effect) as a function of dichotomous ingroup/outgroup categorization, in that outgroup characteristics are not simply additive but interactively determine recognition performance.     

Thought recognition and psychological well‐being: An empirical test of principle based correctional counselling

Aims: To determine the relationship between thought recognition, a major construct of principle‐based correctional counselling, and psychological wellbeing. Method: Following several weekly group sessions of Principle‐Based Correctional Counselling, 54 adult prisoners on probation completed two measures of thought recognition and the Well‐Being Inventory. In a follow‐up study, 30 participants completed the Mindful Attention Awareness Scale. Results: Significant positive relationships were found between both measures of thought recognition and psychological wellbeing and, in the follow‐up study, both measures of thought recognition and mindfulness. Discussion: Possible explanations for the relationship between thought recognition and psychological wellbeing, and thought recognition and mindfulness are discussed. Implications for practice: Teaching correctional clients the principles behind generic human psychological functioning, and the innate design behind human thinking, appears to improve their thinking and draw out their innate healthy functioning.     

Are children’s memory illusions created differently from those of adults? Evidence from levels-of-processing and divided attention paradigms

In two experiments, we investigated the robustness and automaticity of adults’ and children’s generation of false memories by using a levels-of-processing paradigm (Experiment 1) and a divided attention paradigm (Experiment 2). The first experiment revealed that when information was encoded at a shallow level, true recognition rates decreased for all ages. For false recognition, when information was encoded on a shallow level, we found a different pattern for young children compared with that for older children and adults. False recognition rates were related to the overall amount of correctly remembered information for 7-year-olds, whereas no such association was found for the other age groups. In the second experiment, divided attention decreased true recognition for all ages. In contrast, children’s (7- and 11-year-olds) false recognition rates were again dependent on the overall amount of correctly remembered information, whereas adults’ false recognition was left unaffected. Overall, children’s false recognition rates changed when levels of processing or divided attention was manipulated in comparison with adults. Together, these results suggest that there may be both quantitative and qualitative changes in false memory rates with age.

Recognition memory and the mere exposure effect

Repeated exposure to novel stimuli tends to make the stimuli better liked. Examined here is the relation between this increment in liking and recognition of the stimuli. An attempt was made to replicate findings taken as evidence that liking is used as a basis for inferring prior exposure and thus for making recognition decisions (e.g., Matlin, 1971; Moreland & Zajonc, 1977). The claim was not supported. Although in each of five experiments liking and recognition were positively correlated, liking was less sensitive to prior exposure than was recognition. Moreover, statistical analyses suggested that if liking and recognition were causally related, recognition mediated liking rather than the other way around.     

Recognition hypermnesia: The growth of recognition memory (d&#x27;) over time with repeated testing

This study sought to determine whether recognition hypermnesia (unforgetting) might be obtained over time with repeated testing of recognition memory. Four types of stimuli were investigated: pictures or words (captions) from configured (funny) or non-configured (non-funny) cartoons. Three recognition tests, each comprising the same stimulus and distractor items, were successively administered after the presentation of a large set of captioned cartoons. Silent think intervals of 5 min were interpolated between recognition tests. Recognition hypermnesia, measured by increasing d' estimates of accessible recognition memory, was obtained with the pictures from configured (funny) cartoons but not with any of the other groups.
